Buildings have used marble for countless years. Marble is extensively used in architecture and artistic applications; the building industry favours it in particular. Marble is a natural stone that results from the heating and pressure-driven compression of limestone. Huge drills with diamond tips are used to cut through the reserves in the quarries to extract the beautiful stones. Any impurities that are present and run naturally through the stone to form different lines and patterns known as veins. These impurities can be found in a variety of free forms, none of which will resemble the others.
